OF ROCHESTER, OHIO.

'IMPROVEMENT IN WATERiELVEVATORS.

Specification forming part ot' Letters Patent No. 36,189, dated August12, 1362.

K panying drawings, making part of this specilication, in which- Figurel is a perspective View. Fig. 2 is a vertical section, and Figs. Sand 1tare detached sections.

Like letters refer to like parts in the several views.

rlhe nature of my invention relates to the` arrangement of the pawl andratchet to the elongated box for the crank end ot the windlass-shaft,and to the compound lever and brake for raising the shat't and ratchetclear from the pawl while the bucket descends; and to thc arrangement ofthe pawl and ratchet, whereby the pawl is always in contact with -theteeth of the ratchet when the bucket is rising, thus effectuallyguarding against the rapid and dangerous descent of the bucket by thehandv slipping otf the crank. y

A is the' curb. This is made ot frame and boards in the'usual box form.The Windlass B is attached transvcrselyacross the top ofthe curb.

C is the windlass-wheel around which the belt strap or chain winds thatraises the bucket.

D is the bucket.r This is hung by the bail D at a point near the middle,so that it may be easily tipped or thrown to a horizontal position, asindicated by the red lines in Fig. 2. In order to tip the bucket for thepurpose of discharging the water, a finger, a, is secured to thefrontside ot' the bucket, which passes iuside of a hinged rod, b, and as thebucket rises it is discharged of its water in the manner shown in thefigure.

E is a ratchet-Wheel, which is placed on the inside of the curb upon thecrank end of the shaft. The pawl F is also placed on theinside of thecurb and below the ratchet-wheel. The

heel of the pawl projects back from the ful crum-pin' and forms abalanceweight, as seen at F', this part resting upon a pin, c, whichpreventsit from dropping below that point.

G is a box with an elongated opening, in

which the crank end of the windlass-shaft rests, and in which the shaftcan rise just enough for the teeth of the ratchet-wheel Vto clear thetoe of the pawl F. v

When the bucket is ascending, thc journal rests in the bottom of theelongated opening in the box-G, and when in this position the toe of thepawl F is constantlyin contact with the teeth ot' the ratchetwvheel E,so that if the hand of the operator should slip from the crank thebucket could not descend, for the pawl would hold it at any point. g .fH is a lever having its fulcrum I upon the top of the curb about sixinches forward ofthe Y elongated box G,the long arm extending nearly tothe front corner. Theshort arm hasa packing, H', upon the upper side,which, by depressingthe long arm, both Vraises the shaft andratchet-Wheel beyond the reach ot' the pawl, and acts as a brake toprevent the `too rapid descent of the bucket into the well. When thelong arm of the lever His released, the weight ofthe windlass and bucketkeeps the shalt upon the bottom of the elongated opening in the box G,the toe of the pawl at the same time resting in Contact with the-ratchetwheel. K, Vhat I claim as my improvement, and desire to secureby Letters Patent, is-

1. The counterbalance-pawl F and ratchctwheel E, in combination with theelongated opening in the box G, operating as and for the purposespecified.

2. The elongated opening in the box G, in l
